3 point editing is not available when you are not in Normal mode editing
The functions to extract/lift and overwrite/insert has to be available when you are editing with other modalities than Normal mode only. If you decide to adopt a specific mouse behavior by selecting a different editing mode (overwrite or insert) you have not to be forced switching it to "Normal" to use 3 point editing features. I suggest that the extract/lift and overwrite/insert operations are available always whatever is the editing mode you are using.
